Loss was a major part of the book Nectar in a Sieve‚ by Kamala Markandaya‚ and was highly influenced by the Europeans bringing it into India. First‚ the tannery caused many problems for the Indian culture. Many people diffused to India and around the tannery. With so many cultures diffusing into the country‚ it caused the Indian culture to start to decay and for cultural appropriation to occur. Not only did the culture slowly go away‚ but people were killed or died from the tannery. Next‚ because

In this Lab the students were required to do several tests and measurements and then convert these units into other units. There were five tests in all. The first test was measuring the average of three broad jumps in centimeters then find out how many jumps it would take to travel one mile. The second test involved measuring a candy bar (for my group we used a snickers bar) then finding out how many snickers bars end to end it would take to wrap around the equator of the earth. For the third measurement

Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined

Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

An astronomer has a goal to discover and understand the nature of objects in our universe. Astronomers analyze and interpret the information obtained in order to make accurate models of these objects using instruments that collect‚ record‚ disperse and magnify the light that celestial objects give off. In this laboratory I learned how to measure the altitudes of stars using a quadrant. A quadrant is a quarter of a circle that has been divided into 90 degrees. I also learned how to find the angular

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

We measured its relative mass and recorded in our lab notebook. The liquid was consequently poured into the cylinder and the volume measured. To finish off the experiment‚ section three was conducted in order to compare samples of known liquids. Samples of olive oil‚ isopropyl‚ and water were obtained
